A twisting rush of air (4)
I believe the answer is:
wind
'air' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for wind that I've seen before include "take course that's not straightforward? Doesn't sound like it" , "Move on a twisting path" , "Meaningless talk; twist" , "See 7" , "Snake" .)
